Abstract:

[Truncated abstract] Perth is the capital city of Western Australia (WA) and the home of more than three quarters of the population in the state. It is located in the southwest WA (SWWA), a low to moderate seismic region but the seismically most active region in Australia. The 1968 ML6.9 Meckering earthquake, which was about 130 km from the Perth Metropolitan Area (PMA), caused only minor to moderate damage in PMA. With the rapid increase in population in PMA, compared to 1968, many new structures including some high-rise buildings have been constructed in PMA. Moreover, increased seismic acti

Abstract:

We investigated the relationship between seismo-volcanic events, recorded at La Fossa crater of Vulcano (Aeolian Islands, Italy) during 2004-2009, and the dynamics of the hydrothermal system. During the period of study, six episodes of increasing numbers of seismo-volcanic events took place at the same time as geothermal and geochemical anomalies were observed. These geothermal and geochemical anomalies have been interpreted as resulting from an increasing deep magmatic component of the hydrothermal fluids. Four classes of seismic events (long period, high frequency, monochromatic and tornillo

Abstract:

Volcanic rifting environments, such as in Iceland, are challenging for conventional seismic reflection methods using active surface seismic sources. This study demonstrates the potential of a novel technique, called Virtual Reflection Seismic Profiling (VRSP) for imaging reflections in geothermal regions, like Hverahlíð, where a dense seismic array recorded a number of local microearthquakes for cross-correlation. Uppsala University, in collaboration with Reykjavik Energy, recorded seismicity in Hverahlíð using both seismometers and geophones. Acquired data were processed using the VRSP method

Abstract:

Seismic reflection surveying is a powerful method to explore the structures of the Earth’s crust and describe it is layers. It is also used extensively in the oil industry. Offshore seismic profiles were acquired in southern Sweden (Skane area) for petroleum exploration purposes, but no productive fields were discovered in that area. The seismic reflection data were collected and processed in the 1970s. The purpose of this thesis is to reprocess some of the seismic profiles from the 1970s with new processing programs to improve the results and compare it with the previous results. Offshore lin

Abstract:

Moveout velocities sampled frequently along seismic horizons on a selection of seismic lines are used to derive interval velocities in an 'inversion' algorithm developed from work published by Hubral. This inversion is based on zero-offset raytrace modelling in a simplistic local ground model. The 'Hubral algorithm' is incorporated into a database which allows spatial smoothing of velocities. The spatial consistency of derived interval velocities can then be assessed by reference to mis-ties at line intersections, while interval velocities from well data can be used to check their validity.

Abstract:

In Turkey, in most of the reinforced concrete buildings, hallow masonry infill walls are used as a non-structural element, during design stage, their contribution to overall building behavior is not well known. Observations made after the earthquakes revealed that these non-structural elements had beneficial effects on the lateral capacity of the building. In this study, the contribution of the hallow masonry infill walls to the lateral behavior of reinforced concrete buildings was investigated.

However, when the ductility of the elements is activated damage is introduced. Since, the described philosophy has been introduced, a lot of buildings have been designed an

The success in eruption forecasting needs the knowledge of the eruptive processes and the plumbing system of the volcano.

Abstract:

The major objective of this study is to correlate the rocking foundation performance parameters with their capacity parameters and earthquake demand parameters using the results obtained from 142 centrifuge and shaking table experiments. It is found that seismic energy dissipation and permanent settlement of rocking foundations correlate well with rocking coefficient and Arias intensity of the earthquake, whereas the maximum moment and peak rotation of the foundation correlate well with peak ground acceleration. A numerical model, using the contact interface model available in OpenSees, is dev

Abstract:

In regular marine acquisition configuration, shallow sources and shallow streamers are used. Because of this configuration the high-frequency content of the seismic is favored, which is needed for sufficient vertical resolution. If the receivers were deployed at a larger depth the low-frequency content would be favored. The low frequencies are needed for inversion, deep penetration and visualization. However, this configuration would attenuate the higher frequencies and would suffer from poor vertical resolution. The attenuation of either high or low frequencies is a result of the receiver gho

Abstract:

The purpose of this thesis is the development and analysis of smart systems based on electroactive polymers (EAPs). Thanks to their sensing and actuation capabilities, devices based on EAPs, like ionic polymer metal composites (IPMCs), realized by using a noble metal or ionic polymer polymer composites (IP2Cs), where a conducting polymer replaces the metal, pave the road to the development of new integrated devices , being the conditioning circuitry very simple, that could be of high interest in fields such as engineering, biomechanics, aerospace, and robotics. Furthermore, in the near future

Abstract:

Il presente lavoro vuole essere un contributo allo studio dei meccanismi di collasso di pannelli murari sollecitati fuori piano. In particolare si è voluto dare un contributo alla definizione di un metodo di analisi da applicare in maniera efficace su larga scala senza perdere di vista la possibilità di controllare direttamente il fenomeno. L'innovazione consiste nel miglioramento di una metodologia di analisi statica equivalente molto utilizzata, l'analisi limite, che applicata alle murature non consente tuttavia la valutazione della dissipazione energetica. Le analisi svolte hanno dimostrato

Abstract:

Molti degli edifici in c.a. esistenti sono stati progettati in passato per soli carichi verticali o per modeste azioni sismiche e necessitano di un intervento di adeguamento sismico per rispondere ai requisiti prestazionali previsti dalle normative attuali. Nella presente Tesi di Dottorato è proposto e validato un metodo basato sugli spostamenti per l adeguamento sismico di tali strutture mediante l impiego di controventi a instabilità impedita (BRBs, Buckling-Restrained Braces), la cui idea di base è stata recentemente presentata per il progetto di telai in acciaio con BRBs (Bosco e Marino, 2

Abstract:

Il progetto di ricerca, i cui contenuti riguardano il versante orientale dell'area vulcanica del Monte Etna, consiste principalmente in studi geologici di dettaglio per la definizione di modelli bidimensionali ai fini della valutazione della Risposta Sismica Locale (RSL). Inizialmente l attività di ricerca è stata incentrata sulla ricostruzione del modello geologico di questi territori, prestando particolare attenzione alla distinzione tra i terreni di copertura e quelli del bedrock. La Carta geologica del versante orientale dell Etna (scala 1:25.000) rappresenta il più importante risultato ot
